Introduction
Intended Use
Stratos Pro A401B PH is used for pH/mV, ORP and temperature
measurement in industry, environment, food processing and sewage
treatment.
Enclosure and mounting possibilities
• The sturdy molded enclosure is rated IP 67/NEMA 4X for outdoor
use. It is made of glass-reinforced PBT / PC and measures
148 mm x 148 mm x 117 mm (H x W x D).
It is provided with knockouts to allow:
• wall mounting (with sealing plugs to seal the enclosure),
see page 16
• post/pipe mounting (Ø 40 … 60 mm, 30 … 45 mm)
see page 17
• panel mounting (138 mm x 138 mm cutout to DIN 43700),
see page 18
Weather protector (accessory)
The weather protector, which is available as accessory, provides
additional protection against direct weather exposure and
mechanical damage, see page 17.
Connection of sensors, cable glands
For connecting the cables, the enclosure provides
• 3 knockouts for cable glands M20x1.5
• 2 knockouts for NPT 1/2” or rigid metallic conduit
For quasi-stationary installations with Memosens sensors, we
recommend using the M12 device socket (accessory ZU 0822) instead
of a cable gland – it allows simple replacement of the sensor cable
without opening the device.
Sensors
The device has been designed for application with commercially
available sensors with a nominal zero point at pH 7, ISFET sensors or
digital sensors. (It can be easily retrofitted for Memosens sensors.)
